To all whom, it may concern:

Be it known that I, GEORGE J. KIN'D'EL, a citizen of the United States, residing in the city and county of Denver and State of Colorado, have invented certain new and useful Im rovements in Air-Cleaning Apparatus; an I do declare. the following to be a full,

such as will. enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which forms part of this specification.

My invention relates to improvements in apparatus for separating the dust from air, being more especially-intended for use in connection with the removing of dust from carpets or other surfaces or objects in buildings. In cleaning apparatus of this class it becomes of the utm ost importance to remove the dust from the air before allowing the latter to escape, since under ordinary circumstances it becomes impracticable to carry the dust-laden air to a sufficient distance from the buildings where the cleaning is going on to prevent the annoyance resulting ironi the escape of the dust with the air. By virtue of my improvements the dust is removed or separated from the air in an efiicient and economical manner, thus making it practicable to deliver the cleansed air to the air-pump and return it again to the compressed-air tank from which the supply of compressed air is used in house-cleanin systems em loying both compressed air an suction. ere this system is employed, there 1s no escape of the an, since it is used over and over again,

being thoroughly cleansed through the instrumentality of my improvement.

My improved construction, as illustrated in the drawings, consists of a dust-receptacle, a water-tank, and an auxiliary air-cleanswater tot.

ing receptacle connected both with the wator-tank and with the dust-receptacle. This auxiliary Iiaptacle is connected-with the water-taiik both at the top and bottom, the nection bein made to allow the 3 the auxiliary receptacle from the tank, while the top connection permits the escape of the air into the upper part of th=- q water-containing tank. The pure air enter:

the last-nameditank below a fine screenadapted to retard the s lashing of the water, due to the agitation o the latter. The top of this water-tank above the screen is connected with the pump or suction-inducing apparatus. The air, laden with dust, is assed originally into the dust-receptacle beow a screen. In this dust-receptacle the heavier dirt is deposited; but the finer ortion thereof passes u wardl throug a screen diaphragm and thence t ou h a conduit leading downwardly and firm 1y com-' munic sting with the bottom of the air-cleansing receptacle. This communication. with the last-named receptacle is common to both the dust-chamber and water-tank.

Having briefly outlined my im roved construction, I-will proceed to descri e the same in detail,refer ence bcin made to the accompanying drawings, in W 'ch is illustrated an embodiment thereof.

In the drawin s, Figure 1 is a section taken through t e water-tank, the dustchamber, and the air-cleansing rece tacle,

the parts being shown inoperative re ation.

Fig. 2 is a section taken on the line 2 2 of Fig. 1. Fig. 3 is an elevation of the air-cleansing receptacle, illustrating a modified form of construction. Fig. 4 is a fragmentary sectional view of the same.

The same reference charactersindicate the same parts in all the 'views.

Let the numeral 5 designate a dust-chamber having a screen-diaphragm 6 located in its upper portion. A conduit 7 is connected with anozzle 8 at its lower extremity'and at its upper extremity with a dust-chamber be low the screen 6. This nozzle 8 is supposed .to be in contact with the surface to be cleaned or the location from which the dust is obtained, the same being carried to the cham her 5 through the instrumentality of'suction. The chamber 5 is divided by the screen-diaphragm 6 into upper and lower compartmcnts 9 and 10, the latter compartment including by far'the mater-portion of the chamber. Connected with the c0mpartment 9 is a conduit 12, which leads downwardly and enters a T 13, the latter being connected with the bottom of the air-cleansing receptacle 14 by a short conduit 15. The water-containing tank 16 is also connected IQO with the "i" 13 by means of a pipe 17, leading from the bottom of the tank to the T. This T is provided with a partition 18, located between. the extremities of the pipe 15 and the conduit 12.

The receptacle 1 is provided with a periorated diaphragm 19, whose functionis to separate and break up the air, whereby the separation of the dust therefrom is greatly facilitated. The upper part of the receptacle 14 is provided with an outlet-conduit 20, whose upper extremity communicates with the top or the watentank 16 above the wa ter-level and below a screen-diaphragm 21. A. suction-pipe 22 is connected with the up per part of the water-tank above the diaphragm 21. This pipe 22, communicates with an air-pump, (not shown,) but through whose instrumentality the suction is obtained which acts on the conduit '7 and whereby the air is drawn through the entire ap aratus.

.' rom the foregoing description the use and operation of this form of my improved devlce will be readily understood, The dustladen air entering the chamber 5 below the diaphragm 6 is freed from its heaviest dust particles, which drop downwardly into the tank, the dust de osit being designated A.

through this receptacle greatly agitates the.

water and facilitates the air-cleansing operation. This cleansing operation is further as sisted by virtueoi the perforated diaphragm .19, through which theair and water must pass. In the form oiconstruction shown in 1gs.'3 and 4 a nozzle is connected with thecentral part of the (ha hragm 19. This 4 nozzle has a funnelshape lower extremity 24; and an. enlarged upper extremity 25, pro vided at the top with a perforated. diaphragm 26. This or any other suitable device may be located within the air-cieansing receptacle for the purpose of breaking up the air, whereby it is'caused to release the particles of dust. The air after 'passingthrough the receptacle 14 passes with the water out through the conduit 20 and enters the upper extremity of the water-tani 16 below the screen-diaphragm 21 and viinally escapes through the suction-pipe.

Attention is called to the fact that during the operation of the device there is a circuceases lation of water from the tank 16 up through the air-cleansing receptacle 14, up throu h the conduit20, and back into the-topo'i tne tank 16. This circulation is of such a nature as to completely remove all impurities from the air. The air enters the tank 16 aathe top with the water, but passes upwr Qty through the screen 21 and out throughthe suction pipe 22, as heretofore explained. The screen-diaphragm 6 is readily removable for the purpose of removing the dust free-n the chamber 5. The tank 16 is provided with a valve-controlled outlet B for the pur pose of removing the water therefrom after it has become sufiiciently foul to make it impracticable to use it longer for air-cleansing purposes. 7

The receptacle 14 is preferably composed of glass or transparent material inorder that the action of the water when agitated bthe air may be observed by the person in arge of the apparatus.

Having thus described my-imzention, what I claim is 1. In means for separating dust from air,

a twatertank and an air-cleansing recept tor-tank being connected withthesald recap taclc at the bottom to allow the water to eh- I ter the receptacle, the top of the latter being,

in'communication. with the said tank above the water-level, the. top of the dust-chamber being in communication -'with the bottom oi the said receptacle, the dust-chamber having an inlet for the dust-laden air, and suction producing means in corrununication with the water-tank above the water-level, the suc tion acting to cause the air to travel tl'uough the entire apparatus.

2.
